The shorthanded Golden State Warriors rallied in regulation and then in overtime to take down the Dallas Mavericks in a crucial game in the Western Conference playoff picture.

With 13 seconds left in overtime and the score tied at 120, Warriors center Jermaine O'Neal blocked Mavs guard Monta Ellis' runner on the baseline and Golden State guard Stephen Curry won it with a long contested jumper with 0.1 of a second on the clock.

Golden State (46-28), sixth in the Western Conference, played without starting big men Andrew Bogut and David Lee.

Dallas (44-31) fell to ninth in the West despite 33 points and 11 rebounds from Dirk Nowitzki.
